| 摘 要： | 针对L波段高功率线极化径向线阵列天线进行了优化设计.分析了影响阵列天线口径效率的因素,通过三种途径优化了口径效率;同时对单元天线进行适当的优化,减小了阵列天线的反射,提高了阵列天线的整体性能,使其更好地应用于实际.模拟结果表明:经过改进后,阵列天线的口径效率从原来的50.57%提高到85.1%,中心频率上的反射系数降为0.1146,且在513兆赫兹的频率范围内反射系数都小于0.2.

| Abstract: | High power linear polarized radial waveguide array antenna for L-band is optimized in this paper.Factor which affected the aperture efficiency is analyzed,and then the aperture efficiency using three approaches is optimized;at the same time,the array cell structure is adjusted to reduce the reflection,so the character of array antenna is improved,putting it to practice.The simulation result indicates: the aperture efficiency of array antenna was improved from 50.57 percent to 85.1 percent;at the center freq... |
